molten steel oxygen probe oxygen probe

            molten steel oxygen  probe oxygen  probe Product Description oxygen probe used for liquid steel   Oxygen sensor is a kind of metallurgy detection probe which is designed to measure the oxygen content and temperature of the molten steel fast, accurately and directly. 1. Application: Used for primary melting furnace,LF and RH furnaces and so on, oxygen probes measure oxygen activity of the molten steel and the oxygen activity of the molten steel in the treating process, which can guarantee the deoxidizer addition, shorten the refining time, help to develop new varieties, improve technology, and promote steel purity. 2. Main features and range of application: Oxygen sensor has three types: 1)     Oxygen sensor for high ppm 2)     Oxygen sensor for low ppm . 3)     Oxygen sensor for ultra-low ppm. The first one is used to measure the temperature and high oxygen content of molten steel in converter, electric furnace, refining furnace. The second one is used to measure the temperature and low oxygen content of molten steel in LF, RH, DH, tundish, etc. and also quickly measure acid soluble aluminum. The third one is suitable for the steel smelting process which require the ultra-low oxygen content. 3. Principle: "Solid dielectric concentration cell oxygen-content test technology" is applied in oxygen sensor, which allows to measure the temperature and oxygen content of molten steel at the same time. Oxygen sensor consists of oxygen cell and thermocouple. Oxygen content can be calculated from the measured oxygen potential and temperature of the molten steel. 4.  Features: 1) The oxygen activity of the molten steel can be measured directly and rapidly, which is helpful to determine the amount of the deoxidizing agent, and improve the operation of the deoxidation. 2) The oxygen sensor is easy to operate. Measurement results can be obtained just 5-10s after inserting it into the molten steel. 5. Main technical indexes: 1) Oxygen sensor for high ppm Working condition: 1400℃-1760℃ Measuring range: 50ppm~1000ppm Measurement resolution: 0.1mv Measurement accuracy: 0~5mv Oxygen potential: -300mv~+300mv Response time: 8s-10s Measurement efficiency: 98% Measurement efficiency is usually above 98%, but it is related to operations by the workers; if misused, measurement efficiency will be reduced.   Note: If oxygen activity in molten steel is above 50ppm, oxygen sensor for high ppm  is suggested.   2) Oxygen sensor for low ppm Working condition: 1500℃-1760℃ Measuring range: 1ppm~1000ppm Measurement resolution: 0.1mv Measurement accuracy: 0~3mv Oxygen potential: -300mv~+300mv Response time: 8s-10s Measurement efficiency: 98% Measurement efficiency is usually above 98%, but it is related to operations by the workers; if misused, measurement efficiency will be reduced.   Note: If oxygen activity in molten steel is between 1ppm and 50ppm, oxygen sensor for low ppm is suggested.   3) Oxygen sensor for ultra-low ppm Working condition: 1500℃-1760℃ Measuring range: 1ppm~1000ppm Measurement resolution: 0.1mv Measurement accuracy: 0~1mv Oxygen potential: -300mv~+300mv Response time: 8s-10s Measurement efficiency: 98% Measurement efficiency is usually above 98%, but it is related to the operations by the workers; if misused, measurement efficiency will be reduced.   Note: If oxygen activity in molten steel is between 1ppm and 5ppm, oxygen sensor for ultra-low ppm is suggested. If oxygen activity is between 1ppm and 5ppm, oxygen sensor for ultra-low ppm is more accurate than oxygen sensor for low ppm.      Company Information   Founded in May 2002, Shijiazhuang Wanlixin Industrial and Trade Co., Ltd. headquarters in Shijiazhuang, the northern economic powerhouse, which supplies measuring probes and instruments for metallurgy industry. The engineers and professional senior talents constantly improves product system and technology to produce high-quality products. During the development process from single production and management of fast thermocouple, molten steel sampler, to research, develop and produce relevant instruments and probes for oxygen measurement system and hydrogen measurement system, to manufacture equipment in metallurgy industry, the company gradually enlarges and strengthens itself by constant innovation. Our products sell well in about 30 provinces and cities and even in Southeast Asia, Europe, South America and Africa, etc. The company sets up four offices outside Hebei Province, in which 6 professionally trained after-sales teams are equipped. The company occupies a total area of over 46666 square meters. We have 517 employees, including 32 senior engineering and technical personnel. With strong technical force, the company can meet all customers’ demands.   Our company pursues the management policy of “ taking talented person at first, ensuring quality through science and technology, striving for the survival by the quality, promoting development through innovation", adheres to the management idea of “promoting development by stable quality, increasing benefit by reducing the cost” and carries forward the enterprise spirit of “integrity, dedication, and progressive”. With bold innovation, new technology, new materials, new techniques, new methods are applied to ensure product quality. The company's products have passed ISO9001 certificate of quality system. Through constant progress, the company has become one of the professional suppliers recognized and respected by customers.   Warmly welcome old and new friends to visit our company and for business negotiations! We desire to cooperate with you!
